/tmp/temp_7F3C101460D0.d(9,5): Error: template instance `synchronizedMemoize!f` template `synchronizedMemoize` is not defined, did you mean sychronizedMemoize(alias fun)()?

Why the error? Is it compiler bug? DMD v2.084.1

Typo in eponymous template. syc vs sync.

Sometimes, template error messages are hard to get. But this one is pretty clear, to the point that it is difficult for a human to point out clearer. :o)
